Waves and Their Applications in Technologies for Information Transfer
- Physics
This microphone picks up sounds by watching them
This microphone can “hear” by viewing the tiny vibrations made in everyday objects as sound waves strike them.
- Psychology
Listening to slightly different sounds in each ear may boost focus, teen finds
While “binaural beats” may boost attention, his research shows video game music is distracting.
- Space
Scientists caught a black hole ringing like a bell
Two black holes merged, creating a new, bigger one. This event triggered the clearest ripples in spacetime ever observed.
- Physics
Scientists Say: Infrasound
“Listening” for changes in these deep rumblings can allow scientists to predict earthquakes and other geological events.
- Earth
Thunderstorms churn up a ‘boiling pot’ of high-energy gamma rays
A thunderstorm seen in gamma ray vision plays out as a complex, frenzied lightshow above the clouds.
- Space
Here’s how to build an internet on Mars
Future Red Planet residents will need to get online to talk to each other and Earth. But that will require a lot of new tech.
- Animals
Elusive worm-lizards sport weird, spooky skulls
CT scans of these mysterious creatures turned up bizarre internal features. They could offer clues about amphisbaenians’ largely unknown behavior.
- Physics
Let’s learn about particles that help us peer inside objects
Particles such as muons, X-rays and neutrons help scientists peer inside fossils, mummies, pyramids, volcanoes and the human body.
- Space
Check out the magnetic fields around our galaxy’s central black hole
Astronomers have captured polarized light coming from the Milky Way’s supermassive black hole. This offers insight into its magnetic fields.
- Earth
Earthquake sensor: Taylor Swift fans ‘Shake It Off’
Scientists determined dancing fans were behind the seismic waves recorded during Swift’s August concerts.
- Physics
Forests could help detect ‘ghost particles’ from space
If trees could act as natural antennas, one physicist proposes that they just might pick up signals of hard-to-spot ultra-high energy neutrinos.
- Earth
Explainer: Sprites, jets, ELVES and other storm-powered lights
Fleeting glows collectively known as “transient luminous events” flash in the skies above powerful lightning storms.
